I was 15. Messed around with some buddies before that, but they wouldn't fuck me, because they thaught that was too gay. But I lived close to a big sex shop. They had two entrances, the main one at the front, next to the counter, and one in the back, where you could enter from the parking lot, that led directly to the porn cinema and a row of video booths. And though they had video surveillance, if you were quick enough, with a lot of luck you could get inside and slip into one of the booths without anyone knowing you were there. Once inside, I would leave the door ajar, insert some coins, search for bb porn, get out of my shorts and start fingering my hole. Usually it wouldn't take long, until a guy was spying into the booth, rubbing his crotch and waiting for me to ask him inside. And from the porn I was watching it wasn't hard to guess what I was up to...Of cause, most times I didn't get that far, they caught me and threw me out, but the few times I got lucky, I went home with an ass full of mancum...
